Traditional air return columns occupy large spaces and are aesthetically unpleasing. To solve these problems, Berbson invented the 100mm hollow air return unit module. It replaces air return columns and 100mm hollow baffle walls in changing rooms, shoe-changing buffer rooms, etc. With an average return air volume of 500 m³/h, it greatly improves the usable space of cleanrooms. The air return module is prefabricated in the factory, making on-site installation fast and convenient, significantly improving construction efficiency.
